WATER-FILTER.

SPECIFICATION forming art of Letters Patent no. 478,157, dated July 5, i892.

Application filed ma 1s.-1s92.- Serial No- 417,91e. (No model.)

To all whom may concern: Be it known that I, OLAF EASTM N, a citizen of the United States, residing at San Francisco, in the county of San Francisco and- State of California, have invented certain new and useful Improvements in Water-Filters; and I do hereby declare the followingto .be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practicethe same.

My invention has relation to certairnnew and useful improvements in water-filters, as will be hereinafter more fully set forth in the drawings and describedand pointed out in the specification. V

, The object of'my inven islto provide filter adapted tobe secu re(lit?) thd'ordin'ary water or supply pipe, 'whichfshall permit a 20.

to its discharge from the faucet, the first or double filtration to be given to the water prior primary of which shall extract from the water all coarse or heavy foreign ingredients or materialnontained therein, whilethe secondary filtration serves to free the water of 1 all.

impurities contained therein after passing through the primaryfilter or strainer; in so constructing the faucet as to permit of the water being drawn in a filtered or unfiltered reference are used to represent corresponding condition without'change or manipulation of 1 the filter, and,'further, in providing a filter which shall be more efiectual in operation, more durable,and easier cleaned than any of a"si'milar nature heretoforeknown to me.-

Referring to the drawings forming a part of this specification, wherein similar letters of parts throughout the entire specification and several views, Figure-1 is a verticalsectional side view, in elevation, showing the. filter se cured to the'or'dinary supply-p1p e, F1g. 2 1s a side elevation of the faucet with filteringchamberremoved,showingcouplingoruniting joint-in positionto be secured wlthinsupplypipe; Fig. 3, rear elevation of Fig.2, and Fig.

with teeth a of gear 0 secured to outerprojecting end of valve B, which is secured withinopening 0 of the faucet by means of nut d, Fig. 3. In order to limit the rotation of valve B, I provide the stop pin or lug d, which, when the valve has turned its full distance to open or close, contacts with faucetshoulder 01 d during the rotation .of the valve; The upper valve B 'is also provided with a -depending pinnriug-(notshown) which,when

the valve has rotated its full distance, contacts with shoulder or wall e, Fig. 3, and thus limits its movement. The lower valve is cut away, as shown at e, so ,that'when rotated to the position shown in dotted lines, Fig. 1, the central passage b? will be opened, while valve B .is provided with the central openin f. f v To the top of the faucet is secured the filter E, which has secured therein the upper and lower sieveE E the spaceintermediate thereof being filled with charcoal or other.

The valve B; controls suitable filteriugmaterial} Through thismaterial p'asses'the pipe E which forms a continuation of the inlet-passage b. To the top of the filter is-secured the removable cap F, thus forming an upper chamber 1. to the filter and into which pipe E extends.

In order to secure the filter and faucet to the supplyfpipe, I provide theco'upling or uniting joint- F, which is provided-with the screw-threads g g, as' shown in Fig. 4., This coupling is screwed into the inner open end of the faucet until the end thereof abuts with wall g ,-when the opening h, formed'in" the top wall thereof, will be in communication with passage b. The outer end of the co'upling is .then screwed into the'supply-pipe' 5th,:- as shown in-Figl, thus securingthe filterand faucetto said pipe.

In order to prevent and faucet-turning, I provide the key h, which I is secured: between. the walls of ,the faucet.

liability ofi'the has. i

.53 be through passage-way 11 down passage 1),

and thence downward through the filtering and coupling, as shown in the drawings. Within this coupling is secured the strainer orsieve H, which is made removable and serves to prevent heavy or coarse material contained in the water from passing into passage b, consequently keeping samefrom entering into the filter E. Thus the coupling or uniting joint is made to act as a primary filter, which causes the heavy or coarse ingredients contained within the water to settle within the coupling instead of passing into the filter or passage b. 7

By reference to Fig. 3, dotted lines, it will be'iioticed that valves BB are made upon a taper. Consequentlyasthesamebecomeworn bynse they may easily be tightened by turnlug nuts or screws a (Z, thus preventing leak-' age.

The upper valve is controlled and operated by rotation of valve B, inasmuch as segmental gear 0 meshes with gear C Consequently as valve B is .opened or closed.

valve B is turned or rotated in an opposite direction. Therefore when valve B is opened valve B is closed. \Vhen the valve B is opened, the flow of water is direct through 'centralpassage b and out of open end H of the faucet in an unfiltered condition, the valve B" being turned so as to close passageway b. However, by turning valve B so as to close passage-way b valve B' is rotated so as to open passage-way b, asshown in Fig. 1, and the flow of water is then through strainer located in the-coupling into the passage-way b, passing through the open valve into pipe E, from whence it is discharged into chamber f, and from thence the water passes downward through the filtering material into passage-wayb, and is finally discharged from open end H of the faucet in a filtered condit'ion, the water being purified as it percolates through the charcoal contained within the filter. As before stated, the water receives a primary filtration by passing through the strainer or sieve located within the coupling. The sediment deposited within the coupling may easily be removed by opening valve B and closing valve B which gives a direct flow through passage-way b and thus carries away all deposit contained within the coupling.

In order to thoroughly clean my filter, the cap F is removed, also key 71, and the filter and'faucet turned upside down. Then by the operator placing hand over opening H and 'opening valve B the dew of water will material, causing the accumulated sediment to be washed therefrom. After the material has been thoroughly cleaned the valve B is closed and valve B opened, which causes a flow of water through strainer H ,passage 1), valve-opening f, and pipe E thus washing out these parts, if found necessary.

It will be noticed by reference to Fig. 2 that do not always intermesh, but only do so when it is desired to open one and close the other.

When the handle is thrown to position indicated by.O the valve B is opened and valve B closed, inasmuch as the gear-teeth intermesh when valves are rotated, while when handle is thrown. to position indicated by G, then both valves will be closed. By the forward down movement 0 the lower valve B is opened and valve B remains closed or undisturbed by such movement. It will thus be observed that by the movement of the handle I can open only B, so as to give a direct flow through the faucet properor by its movement may open one valve and close the other, or cause both valves to close, and-thus completely stop flowof water.

Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent of the United States, is-

1. The combination, with the faucet having one end forming an inlet and the other formin g an outlet, the passage 1), leading upward from the inlet, the passage 19 leading directly from the inlet to the outlet, and the passage 12, leading from the top of the faucet to the outlet, of valves mounted in the passages 11 b and a filter secured on the faucet and communicating with the passages 19 b.

H 2. The combination,-With the supply-pipe,

of a faucet having a plurality of water-passages, a filter secured onthe faucet, a coupling connecting' the faucet and the supplypipe and provided with alongitudinal strainer, and valves mounted in the water-passages and adapted to force the water through the filter -or direct1y through the faucet.

3. The combination of the faucet having passages b 1) W, a supply-pipe, aeoupling connecting the supply-pipe and the faucet and provided with a longitudinal strainer, valves mounted in the passages b b, and a filter secured on the faucet and having a central pipe forming a continuation of the'passage b.

4. The combination, with the faucet provided with water-passages, filter secured thereto, removable cap secured to the filter, pipe passing through the filtering material and having its discharge in a chamber thereabove,

said pipe forming a continuation of the filterpassage of the faucet, rotatable valves sooured within the faucet and controlling the water-passages, said valves connected so that the opening or one erases theotl'ier, anus 0011' pling forming connection between the faucet and supply-pipe and of the strainer located,

therein, as and for the purpose set forth.

In testimony whereof I afii'x my signature in presence of two witnesses,
